Spamcop blocks IP addresses based on spam complaints, spam traps, and user reports, with its blocklist widely used for email filtering. Being listed can severely impact deliverability. Causes include spam reports, poor list hygiene, compromised accounts, and shared IP issues. Resolving requires stopping spam, identifying and fixing root causes, and requesting delisting. Proper email authentication (SPF, DKIM, DMARC), infrastructure configuration, monitoring, and relevant, compliant content are crucial for prevention. Carrierzone is noted for poor deliverability and difficult customer service, suggesting alternative providers may be necessary. Consistent volume, feedback loops, and analyzing bounce messages are also important for maintaining a positive reputation.
